    GLEEBLE system for physical simulation and thermomechanical characterisation in metallurgy processes

    Sistema GLEEBLE de simulación física y caracterización termomecánica en procesos metalúrgicos

    TECNALIA’s GLEEBLE 3800 system is a physical simulator of thermo-mechanical processes in metal alloys, such as hot rolling, forging, hot stamping, HAZ in welding and the mapping of forming.

    Description

    The system is made up of the following equipment:

    • Mobile conversion unit.
    • Transformer.
    • Test chamber (vacuum and controlled atmosphere).
    • Mobile axis.
    • Servo-hydraulic system.
    • Hydraulic pump.
    • Water cooler.
    • Channels for thermocouples.
    • Load cell.

    There is also an external hardening system, and axial and diametral strain gauges.

    It has a tool for anchoring the different clamps (cylindrical and flat test specimens) for hot tensile tests, SICO tests, post-deformation dilatometry tests, thermal fatigue tests, etc. As a secondary tool it has an adapter for compression tests.

    Its main characteristics are:

    • “Direct resistance” heating thermal system (heating speed up to 10,000 ºC/s)
    • Mechanical system with precise control of mechanical variables (axis movement, applied force)
    • Transverse isothermal planes. Axial temperature gradient.
    • Process simulation: hot rolling, forging, hot stamping, HAZ in welding and the mapping of forming, etc.
    • Materials testing: thermal cycle tests, hot tensile tests (ductility), hot uniaxial compression tests (true stress-deformation curves), susceptibility cracking (SICO) tests, post-deformation dilatometry tests, thermal fatigue tests, fusion and solidification, etc.

    Aimed at:

    • Companies devoted to manufacturing or transforming metal alloy products by means of thermo-mechanical processes. In particular, foundry and steel processes.
